understudy SKILL.md skillA
understudy from understudylabs/orchestra-agent-tools is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when a developer asks a coding agent to improve an LLM app or agent — "make my LLM app cheaper/faster", "raise quality or reliability", "compare models", "pick a model or route". Orchestrates trace → evaluate → optimize (GEPA, automatic prompt evolution) → compare → deploy via worker skills. Not for generic coding unless LLM behavior, cost, traces, evals, or routing is involved.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Orchestra Orchestra is agent improvement infrastructure: it helps a coding agent improve its developer's LLM system from real traces. This skill is the orchestrator — it gives your agent the loop and routes each stage to exactly one worker skill. It does not do the work inline. The loop is backend-agnostic: it can begin locally without registration, but the default route is the strongest active model and managed cloud execution when the developer has not selected Local. A dropped dataset authorizes analysis through the active model. Activating a named, bounded cloud workflow authorizes its normal uploads, provider calls, temporary resources, evaluation, receipts, and cleanup. ## The improvement loop 1. Understand the codebase — find where LLM calls happen and the current model / provider / harness / routing / eval setup. 2. Understand the objective (cost, speed, quality, reliability, compliance, or a weighted mix). 3. Understand the constraints (what must not be violated). 4. Understand the workload — inspect prompts in situ, trace the request/response code path, profile the dataset/traces, and confirm the task meaning with the user. …

How to install
mdr add understudylabs/orchestra-agent-tools/understudy@sha256:d38e10b624c73d0dThe line at the top of this page pins the label git:20261027.533318e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
